Method to bypass the browser cache

At times it’s necessary to manually force a non-cache reload/refresh of a page, overriding what browsers (wrongly) interpret as when the last change of a site happened. (The cache is a temporary storage area where frequently accessed data can be stored for rapid access in our hard drive.)
To do this in FireFox, hold down SHIFT and click the RELOAD button. In Internet Explorer, hold down CTRL and click the REFRESH button. Other browsers can allow this quick bypass which I was glad to discover, very handy and much simpler than erasing the whole cache. Check these instructions containing others like Safari, Chrome, Konkeror and Flock.
